What are the x-intercepts of the function f(x) = –2x2 – 3x + 20?(–4, 0) and
and (4, 0)
(–5, 0) and (2, 0)
(–2, 0) and (5, 0)

Answers

Answer 1

Answer: If you would like to find the x-intercepts of the function f(x) = - 2 * x^2 - 3 * x + 20, you can calculate this using the following steps:

f(x) = - 2 * x^2 - 3 * x + 20
f(x) = - (2x - 5) * (x + 4)
1. x = - 4
2. x = 5/2

(x, y) = (-4, 0)

The correct result would be (-4, 0).

Answer 2

Answer:

The x-intercepts of the given function are (2.5, 0) and (-4, 0)

Solving quadratic equations

From the question, we are to determine the x-intercepts of the given function

The given function is

f(x) = –2x² – 3x + 20

To determine the x-intercepts of the function, we will determine its zeros

That is, we would solve

0 = –2x² – 3x + 20

This can be rewritten as

2x² + 3x - 20 = 0

Solve by factoring

2x² + 8x - 5x - 20 = 0

2x(x + 4) -5(x + 4) = 0

Then,

(2x - 5)(x +4) = 0

2x - 5 = 0 OR x +4 = 0

2x = 5 OR x = -4

x = 5/2 OR x = -4

x = 2.5 OR x = -4

Hence, the x-intercepts of the function are (2.5, 0) and (-4, 0)

What is the value of 6P6? A.1 B.36 C.720 D.46,656

Answers

$the\ permutationon:\ \ n\ P\ x= (n!)/((n-x)!) \n \n6\ P\ 6= (6!)/((6-6)!) = (6!)/(0!)= (2\cdot3\cdot4\cdot5\cdot6)/(1)=720$

$Ans.\ C$

The value of 6P6 permutation is 720 .

To calculate the value of 6P6 ( permutation of 6 objects taken 6 at a time ), we can use the formula :

nPn = n !

where n is the total number of objects .

In this case, n = 6. So, substituting it into the formula :

6P6 = 6 !

Calculating the factorial of 6 :

6! = 6 × 5 × 4 × 3 × 2 × 1

= 720

Therefore, the value of 6P6 is 720 .

Hence, the correct answer is C . 720 .

in sound and harmonics, the frequency of a vibrating string varies inversely to its length. A guitar string 20 inches long vibrates at a frequency of 400 cycles per second. Find the frequency of a 35- inch string.

Answers

20 inches is 400
10 inches is 200
5 iches is 100

So 20+10+5=35
Which means 400+200+100= 700

So the frequency of a 35 inch string is 700 cycles per second

Can someone answer these plz.
